This inventionrelates to shuttle feeler thread" parters and; clamps employed in filling, the shuttle feeler moves to its shuttle feeling position and the parter and-clamp are actuated to .part the filling leading to the shuttle box and clamp the end leading to the cloth selvage, with the result that when the shuttle feeler moves to its initial or front position, the end of filling leading to the clothselvage is positioned for the actionj of ing member to clamp the thread It has 'heretofore'a'lso been common to provide a shuttle feeler thread parter and clamp that would first clamp the thread of theoutgoing r filling carrier or bobbin and then cut it.j':'

One "of the objects of the present invention is to providea shuttle feeler thread parter andyclamp, comprisingparting and clamp mg members, and afcomb ned parter and portion of the'parter andclamp with s'cored or' grooved surfaces which will act, as the clamp pivotally associated with the shuttle feeler' between the parting members, and havingia cutting edge onone face thereof and "a clamping face on the opposite side,

the edge of whichextends beyond or below the parting edge. 7

When the thread has been cut and clamped by the shuttle feeler thread parter and clamp as heretofore constructed, itimay' happen at times that the clamped end may not be fully released when thejfeeler moves to its "shut tle feeling position, in consequence of which the end of filling previously leadingto the cloth selvage is liable'to be drawn into the shed and form imperfect cloth. Another featureflof the present invention, therefore, consists in providing the thread clamping parter opens, 'to lift the end offilling from between'the parting members andinsure' its release from between the clamping surfaces, i The above and other novel features 'of rthe V a. invention and new combination of parts will v best'be made clear from the following detends. a pin 9, whereby the thread parter ordinary practice toprovide scription and the accompanying of one good form thereof.

The shuttle feeler 1 be of usual construction and having its shuttle feeling end formed'withta recess between the iaws 2 and 3 for engagement with the shuttle should it not be properly boxed. and for positioning the outgoingfilling end for the. action of the thread parter and clamp. n I

As hereinbefore noted, the shuttle feeler is caused to moveinto its rearward shuttle feel:

ing position onicall for, replenishment of filling, but the meansfor effecting thismove ment is not herein shown and described-be.-

cause the details thereof formfno part of the present invention and are nowwell understood by those familiar with the art.

The shuttlefeeler, in: accordance with the pres-:

ent invention, has mounted thereon the. A

is mounted on the shuttle ffeeler a fixed thread parter and clamp, and, asshown in thread 'partingmemberf f, and similarly,'a

fixed thread clamping member 5, between which is pivotally mounted the combined thread parter and clam 6.- a n 1 Extending laterally rom theshuttle feels er is a bolt or pivotaljsu'pport 7 on which the combined thread parter and clamp 6 is pivotally mounted, and extending rontwardly of the pivotal support? is the downturned or tail portion 8 ofthe combined thread parter and clamp, from which ex embrace a stud or pin 19. eXtendinglatera1- ly from the shuttle feeler through an opening 13 formed in the front portion of the combined threadparter -and clamp 6, the construction bein such'that in the present form of the invention, the clamping member 5 is held in fixed position. f s V p I The combinedthread pa'rte'r and clamp 6 is mounted on its pivotal support 7 be tween the clamping member 5 and the parti ing member e, and a spring washer 14C interposed' between the head of the pivotal inipport and the clamping member 5 malntains the parts in; QO-YfiltttGClOPGltltlVQ relation. V r

.The combined thread parterend clamp 6 is of novel. construction and is formed as a single member provided with a, part5 ingedge on onefface and a clamping pora011 on'its opposite face, thelower edge of which extends beyond the cutting edge of the parter, as indicated in Fig. 1'. 4

.The combined. thread parter and clamp 6 may be, conveniently formed ofa single piece of material, and on theface thereof,

for coeperation with the associated parting member 4L, the thread parter' andclamp 1s provided 'withthe cutting edge 15, which may be formed by cutting away a portion of the. combined thread parter and clamp onthe'face ad acent the parting member 4:,

, as indicated at 16. The opposite side of the combined thread parter and clamp 6 is extended downwardly as at l'Z beyond .the cut- I tinp edge 15, with the result that when the.

feeler is in its backward shuttle feelinglpo srtion and the tail port on 8 of the combined thread parter and clamp is struck by the layer :1 part mounted thereon, the combined thread parter 'an'd clamp will be turned up on its pivotal support 7 to first clamp the filling between theextended face 17 andthe adjacent face of the clamping member-'5, and as the combined threadvparter and clamp moves to full closed position, the cut ting edge lfiwill cooperate with the parting member i to part the filling leading to the fil-lii-n; carrier to be abandoned v \Vhen the shuttle feeler moves to its rearward feeling position, it desirable that the filling leading across the end. of the shutv feeler shall not be displaced by the end ofthc comhinedthread 'parter and clamp,

and to respond to such condition, the combined thread parter and clamp 6' is provlded with a roundedtno'se'lfi which, if struck by the fillin! the shuttle feel er moves to its rearward shuttle feeling position, will defleet the filling downwardly into cutting and clamping position. p As hereinbefore stated, the combined thread parter and clamp 6 may be formed of a single piece of material, such as metal, and have at one side thereof the cutting edge 15, while the opposite side is extended downwardly beyond said edge, to form the clamping portionlof the combined thread parter and clamp, to cooperate with the clamping member 5 to clamp the thread. be-

fore it is parted, and such construction-is -1Dl101t61 in Flg. 1. e

:Itis not always necessary, however, to

make the combined thread parter and clamp 6 of a single piece of material, because the clamping face thereof may be formedby an insert made in the side portiono f the. com

bined thread parter andYclamp, as indi'cated IIIF1gr5, Theinsert 19, Fig. 5,. may be con veniently secured to theside portion. of the thread parter and clamp, and a preferred manner of making such connection between the insert and side-of the thread parter and clampis to weld the insert 19 into a. suitable recess formed in-theside face of, the com bined thread parter-and clamp, as indicated in Fig. 5. In such case, thejlower edge 20 low. the cutting edge 15. of the combined thread parter and clamp, with the result that in the modifiedconstruction, as indicated in Fig. 5, the thread. will first be clamped between thedownwardly extended side portion of, the insertand the-Fadjacent clamping member 5 before the cutting edge '15 parts the filling in cooperation with the parting member 4, hetherthe combined thread parter and clamp 6 be made of a single piece of material or whether an insert such as 19 be secured to the side of the thread parter and clamp :asby welding, Or. otherwise, the parts are integrated and form single combined parting andvelamping mem her, the essentials in either case being that the lower edge of theclamping portion of the combined part-er and clamp shall extend a substantial. distance below the cuttingedge 15 "onthe opposite face of. the parter and clamp; V

It" happens at times, especially with some characters or kinds of filling,.'that when the end leading'to thdclothSelvage has been clamped hetween'theclamping members, and the clamp is opened, the end of the previr ously clamped filling may not become d tached from the clamping members, but, on

the contrary, willadhere to oneof them, especially wherev one of the clamping'mem hers is formed of fibroid material such as of the, insert, Fig, 5, extends beyond or be* 7 Fig.3, andraise the previously clamped endv ,isnow inco'mmon use, To :avoidthis contingency,-fthel extended side: face 17 which forms the clamping portion of the combined thread parter a'nd clamp-is provided w th a scored or. grooved lifting. surface, as indicated, at 21, and Suchscores or grooves thus formed 111- the-"clampmg-v surface are preferably arranged to extend transversely of the filling av when it is clamped between 10 the clamping surfaces. Such scores or grooves not only insure a grasp of the filling as the clamping members are closed and thus secure the full clamping action on the end leading to the cloth selvage, but when the clamping members are separated or opened .and the, filling end previously clamped is to be released, such scores or' grooves act as a thread lifter, as indicated in of'filling a as the movable.clamping member rises to its open or 'unclamping position; V p The character of the clamplng member 5 -which cooperates with thedownwardly extended clamping surface 17 on the side of the combined parter and clamp 6, may be varied. It may, for instance, be formed of fibroid material or-otherwise provided with "a clampingportion on its inner face to cooperate with, the clamping surface 17 on the side ofv the combined thread parter and clamp, and in case the clamping portionof the clamping member 5 is a substantial distance below the top of the clamping member 5, the downwardly extended, side surface portion 17 of the combined thread parter" and clamp will act effectively to clamp the thread before it is parted. r

When the shuttle feeler is moved to its rearward feeling, position, the combined thread parter and clamp is open, as indicated in'Fig. 1, and'the fillingjwill be positioned for the action of the thread parter 1 and clamp. As the lay moves frontward,

the tail portion 8, in the present instance of; the invention, will be struck by the 'layor a part thereon, and cause the combined thread parter and clamp '6 to move to its closed position, as indicated in Fig. 2, thereby first clamping the thread a between the,

scored extended surface17 at the side of the thread parter and clamp and the clamping member 5, an-das the combined thread parter and clamp moves further to its closed posi-. tion, the cutting edge 15'at the'opposite side of the combined thread parter and clamp will cooperate with the cutting member 4 to cut the thread, as "indicatedin'Fig. 2, and

the clamped portion of the threadwill be securely held between the scored or grooved, surface 17 and theclamping member 5; The

filling end having been parted and clamped,

as above stated, the shuttle feeler will move to front position to hold the end leadingto the cloth selvage for'the action of the temple the parter andclamp are opened. ,3.
